The 97th Indianapolis 500 entry list was officially released Tuesday, in a departure from previous years when it has been announced in April. There may be revisions for the field to hit the 33-car number for the race.

The only new arrival to the list was a second Ed Carpenter Racing entry, with no driver listed.

Buddy Rice, the 2004 Indianapolis 500 champion who had been linked to a third Schmidt car, was not listed. Expected or anticipated announcements for several other rumored drivers – Bryan Clauson, the Lazier brothers (Buddy and Jaques), Jay Howard and/or Katherine Legge – have also failed to materialize at this point.

In total, the list includes three former 500 winners (three-timers Helio Castroneves and Dario Franchitti, and 2008 champion Scott Dixon), and four 500 rookies (AJ Allmendinger, Carlos Munoz, Conor Daly and Tristan Vautier).

The entry list breakdown by team and engine manufacturer is below. All 33 cars also have a “T” car, a spare, listed.
